reassign 521883 adduser retitle 521883 Should accept underscores in usernames by default thanks Quoting Christophe (christophe.curis@free.fr): > Package: installation-reports > Severity: wishlist > > Hello, > > When prompted for the login of the first user, a check is performed to ensure it is valid. > However, the character '_' (underscore) is rejected. > Is it thinkable to have it accepted? Underscores are not accepted by default by the "adduser" command in Debian (adduser is a high level command to create users, that's built on top of the standard useradd commant from the passwd package. The installer team decided to stick with the default behaviour of adduser. If an underscore is acceptable, then accepting it should be implemented in adduser before the installer accepts it. I reassign this bug to adduser but I think this has been debated many times already....I just prefer leaving the answer to adduser maintainers
